Intravaginal Electrical Stimulation in Idiopathic Overactive Bladder
Bladder Training With and Without Intravaginal Electrical Stimulation in Women With Idiopathic Overactive Bladder: A Prospective Randomised Controlled Trial
Overactive bladder (OAB) is a symptom complex defined as urgency, with or without urge urinary incontinence (UUI), usually with frequency and nocturia, in the absence of urinary tract infection. Currently, a wide range of therapeutic options exist for the treatment of OAB. These include first-line conservative (physical) therapies which focus on electrical stimulation (ES) and behavioral therapies such as lifestyle modifications, bladder training (BT), pelvic floor muscle training with or without biofeedback, second-line therapies which are pharmacologic, and third-line therapies which either neuromodulate or chemodenervate the bladder.
In clinical practice, BT and Intravaginal ES (IVES) are frequently used together in the treatment of women with OAB, but the evidences/results of the combined (BT+IVES) use of these two treatment options are so rare that they can be neglected in the literature. There is only one study including BT+ES treatment arm (one of the four treatment arms) in women with idiopathic OAB in the literature. In a study, BT+ES was not found to be effective both from BT alone and from the untreated control group. While interpreting the results of this study, it should be take into consideration that patients treated received relatively few treatment sessions (nine treatment sessions, once weekly) in this study. In addition, in the light of authors clinical experience, the investigators think that this issue is still open for research. Moreover, there is no recommendation on conservative combinations in the guidelines due to insufficient data.
This study is the first prospective randomized controlled trial that compares the efficacy of BT and BT plus IVES in women with idiopathic OAB. In this study, the investigators aimed to evaluate the efficacy of BT with and without IVES on incontinence-related QoL and clinical parameters in women with idiopathic OAB.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |

Other: Group 1: Bladder Training - Control group
Specific goals are to correct faulty habit patterns of frequent urination, improve control over bladder urgency, prolong voiding intervals, increase bladder capacity, reduce incontinence episodes and restore patient confidence in controlling bladder function

Bladder Training
|
Active Comparator: Group 2: Bladder Training+Intra Vaginal Electrical Stimulation
IVES was performed in lithotomy position via Enraf Nonius Myomed 632 device with a vaginal probe.
IVES sessions were performed three times in a week, for 8 weeks.
Every session lasted 20 minutes.
The intervention comprised a 24-session treatment program of ES.
The stimulation parameters were frequency at 10 Hz, a 5-10s work-rest cycle and 100 ms pulse width.
The symmetric biphasic pulse wave could be delivered over a range of 0-100 mA.
The intensity was controlled according to patients' discomfort level feedback
